Questions buyers ask

Before you request a quote

Which processor does my LED wall need?
It depends on the panel resolution and the number of receiving cards. Tell us the wall size and pitch and we match the sending card or all-in-one processor.
Do you configure it?
Yes — every processor we sell is configured and tested with the wall before handover.
How long does installation take?
Most indoor walls up to 10 m² are installed and calibrated in one to two days; outdoor boards depend on the structure and permits. We survey the site first and confirm the schedule in the quote.
What warranty do you give?
Official manufacturer warranty on panels and controllers, serviced by our own engineers in Kathmandu with spares in stock. Warranty terms are itemised in every quote.
Do you deliver and install outside Kathmandu?
Yes. We have installed in Pokhara, Butwal, Bhairahawa, Dang, Dhangadhi, Lumbini and across the valley. Delivery and travel are itemised in the quote.

Tell us the wall.
We'll size the screen.

Share the space and viewing distance — we'll reply with a pixel-pitch recommendation and an itemised quote within one working day.
